Student needs advice - mail stuck in outbox

[kc7whd]

I'm starting to study for my MS Exchange 5.5 cert, and have run into a snag.

Started from newly formatted drive partition, and installed NT 4.0.
Installed NT Service Pack 4
Installed Demo version of Exchange 5.5
Opened up User Manager for Domains, and set up several user accounts, which of course enabled me to set up corresponding Exchange mailboxes as well.
Open up the simple Inbox client, and set up profile: entered User name, selected Exchange Services, and specified the server (which in my case is the local computer) and the profile name, to correspond with the user name.
Profile was set up successfully, and Inbox started up. I started a new email, and selected the recipient - my self, or one of the other users I previously set up; both showed up automatically in the address book, of course. Before the email was sent, the recipients's names were underlined. I attempted to send email many time, but they just sit in the outbox.
I'm not trying to send Internet email, just internal messages via Exchange. TCP/IP protocol is set up properly, and I have a small, but functioning network with a few clients - various versions of Windows. I had the same result with these, even though they were able to "see" the address book that I set up on the server. What's going on?

Did I forget something?

I'd really appreciate some help with this!

Thanks!

sounds like your MTA is not on, check it and try bouncing it (stop and start the service)

The MTA is not involved with mail all on the same server. Go to support.microsoft.com, and search for "RPC binding order." That may not be the problem either, but it's more likely.
